My apologies.  "gcc" doesn't know about the Pascal run-time library, which 
is needed to resolve the externals you listed.  You can either tell "gcc" 
about the Pascal library:

  gcc footest.c foo.o -o footest -lgpc

...although that depends on "gcc" being able to find "libgpc.a" in its 
default search paths, or you can have "gpc" run the linker ("gpc" already 
knows about the Pascal library):

  gcc -c footest.c
  gpc foo.pas footest.o -o footest
